Knock knees
Alternative Names
Genu valgum
Treatment
Knock knees are usually not treated. Surgery may be considered for knock knees that persist beyond late childhood and in which the separation between the ankles is severe.
Outlook (Prognosis)
Children normally outgrow knock knees without treatment, unless there is an underlying disease. For cases requiring surgery, the procedure provides excellent cosmetic results.
Possible Complications
- Difficulty walking (very rare)
- Self-esteem changes related to cosmetic appearance of knock knees
- If left untreated, knock knees can lead to early arthritis of the knee
When to Contact a Medical Professional
Call your health care provider to schedule an evaluation if you suspect your child has knock knees.
